Hello All. I am trying to run a parallel application that should use one core less than the no of cores that are available on the system. Are there any flags that i can use to specify this.
i tried using the following syntax with machinefile openmpi-1.4-BM/bin/mpirun -np 14 -npernode 7 -machinefile machinefile ven_nw.e <coll.dt5. This fails. Is there any other way around this. When i get two nodes (with 16 cores) allocated from SGE and we want to use only 14 cores out of the 16 allocated.
